Mine Stray Current Tester Price Technical Parameters:

Measurement Range Current Gear 0-50mA-250mA -1A-5A-10A

Voltage Gear 0-0.2V-1V -4V-20V-40V

Measurement Accuracy AC ±5%

DC ±2.5%

Usage Methods and Precautions:

1. Before measurement, screw the test rod wires into the two binding posts respectively, and adjust the meter pointer to the zero scale line.

2. Place the test rods connected to the binding posts on the two points to be measured (e.g., rails, water pipes, cable sheaths, coal, earth, etc.). The two test points should be on different conductors, with a distance of about 2 meters. Normally, measure every 50-100M, or temporarily determine test points as needed. Set the switch to the appropriate gear, and the meter reading, after conversion, gives the corresponding current value.

3. During measurement, ensure good contact between the hard alloy tip of the measuring probe and the object under test. The instrument should be placed horizontally to ensure accurate readings.

4. When AC stray current is not detected at a location, also test for DC stray current, and vice versa.

5. When measuring stray voltage values, the gears correspond as follows: 50mA corresponds to 0.2V, 250mA to 1V, 1A to 4V, 5A to 20V, and 10A to 40V. (i.e., current value multiplied by 4 gives the voltage value)

6. When the magnitude of stray current is unknown, first set to the maximum range gear, then gradually decrease until an appropriate measuring gear is reached.

7. When the measured current exceeds 5A, the instrument should only be used for short-time measurements. When the measured current exceeds 10A, the instrument should only be used for instantaneous measurements to avoid burning out components and the meter due to high current.

8. When measuring DC stray current, if the meter pointer deflects in the reverse direction, swap the test leads.

9. When the instrument is not in use, set it to the "Off" position.
